To (ill whom it may concern:

Be it known that I, CHARLES LIcH'rEN- STADT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Rewindin Fabrics, of which the following is a spec cation, reference being had to the accompanying drawings.

August 18, 1903, my invention in its broadest aspect is not restricted to use with such machine, as it may be employed in any other situation to which it is adapted.

My invention, broadly considered, consists in providing improved means for e ualizing the power applied to the rewin ingmandrel.

Morespecifically, it. consists in providing driving rolls or cylinders at opposite sides of themandrel arranged to engage the fabric thereon from above and below and by their frictional engagement to cause it to rotate.

It also consists in providing means for applying ower axially to the mandrel instead of to t e fabric thereon, thereby preserving the fabric from contact with the rolls.

It further consists in providing frictionclutch mechanism between the source of power and the-mandrel for regulating the speed of the mandrel, and consequently the tension upon the fabric.

My'invention also includes certain other features, which will be hereinafter set forth.

In the accompanying drawings, which illustrate the application of my improvements to the machine illustrated and described in my patent above referred to, Figure -1 is a partial side elevation illustrating my improved form of rewinding mechanism, in which I employ positively-driven rolls at opposite sides of the rewinding-mandrel. Fig. 2 is a view similar to Fig. 1, taken at the opposite side of the machine. Fig. 3 is a partial end view of the construction shown in Fig. I; Fig. 4 is a artial horizontal section on line 4 4 of Fig. 2.

rewin ing-roll. .Fig. 7 is an enlarged side rewindin mechanism in which the rewinding-man rel is driven by power applied axially thereto and is-provided with means for regulating the tension upon the fabric. Fig. 8 1s a vertical section on line 8 8 of Fig. 7. Fig. 9 is a pers ective view illustrating the manner in whic several parts of the rewinding mechanism shown in Fig. 7 are mounted. Fig. 10 is a sectional view illustrating the manner of removably supportin the positively-driven mandrel in place. i 11 is a perspective view of the removab e block shown in Fig. 10. Fig. 12. is a partial sectional view illustrating the manner of securing the u pier end of said removable block in place, an ig. 13 is a section on line 13 13 of It may be well to explain that the machine in connection with which my present improvements are illustrated, and which is fully comprises a pair of presser-rolls operating in connection with vertically-movable frames adapted to hold bars of water-repellent composltion, said bars being arranged below said presser-rolls. The arrangement is such that and the opposite bar of composition, first one surface of the fabric being treated and then the other, after which it passes between a pair of cylinders and thence to the rewinding mechanism. The barsof composition are pressed up against the fabric by counterbalance weights carried in suitable frames which are so arranged that the weights may be adjusted to vary the pressure of the composition upon the fabric. When desired, the weights may be locked againstoperation by locking-levers. The presser-rolls are geared 5 to the calendering-cylinders, which are in turn driven from a maindrive-shaft. A numb er of such parts are shown in the drawings for the sake of clearly illustrating the general construction of the machine to which my improvement may be applied. For example, 20 21 indicate the side frames of the ig. 5 is an enlarged detail illustrating the ig. 6 is an enlarged etail illustratin the guiding mechanismfor the upper view illustrating a more lmproved form of machine; 23, the legs which support the side illustrated and described in my said patent,

" 42, parts of the frames which'suoport said bars; 47, one of the presser-rolls; 48 49, pivoted bars in which the pressenrolls are journaled; 50, one of the pivots of said bars; 66', 67, 68, and 96, a series of gears by which the presserrolls are driven from a gear 95, mountedon the shaft of the lower calendering-cylinder 91; 98, the main drive-shaft connected with the gear 95 by a pinion 97 90, the upper calenderin -cylinder, and 94 a gear connecting said cylinder with the gear 95. The unter+ balance-frames are indicated by 70 and 71, the counterbalance-weights by 69, andthe adjusting devices for adjusting said weights .by 81 82. I

, 88 indicates the lever for locking the counterbalance-weights against operation, and 86 the arm of said lever, through which it operates. The arm 86 may be thrown up against the frames 70 or 71, as the case ma be, byoperating the lever 88, thereby hol ing said frames against movement.

111 indicates a lever for vertically adjusts ing the upper calendering-roll, said lever acting throug which extends across the frame of the machine. Said cranks are connected by links 108 with levers 105, which are pivotally supported at their inner ends and extend under the bearings of the upper calendering-roll.. When the parts are in t Fig. 2-, said calendering roll is in its operative position, and I are at an acute angle to each other, as. shown. By operating the lever 111 the shaft 110 IS rocked, bringing the cranks 109 and links 108 more nearly into line, thereby elevating the levers-105 and raising the upper calenderings 118 indicates the rolls which engage the fabric as it passes up over the up er calendere ing-roll 90, all of which are ful y illustrated and described in my said patent and separendering-cylinders 9O 91.

ately form no part of my present invention.

. 122 indicates a mandrel on which the fabric is wound after it passes between the cal- As shown in Figs.

- 1 and 2, the mandrel is arranged to rise vere tically between u rights 123 124, carried by the side frames 2 21 at each side of the cylinder 90. The upright 123 is rigidly secured to a suitable standard 125, while the upright I 124 is pivoted to a standard 126, secured to the side frame on which it is carried. It will be understood that similar uprights'are pro v vided at each side of the machine. By this construction the uprights 124 may be turned down for. the removal of the mandrel with the roll of fabric wound upon it. The up rights are locked together inoperative position by a spring-latch 127, as shown in Fig. 1.

Coming now to the description of my pres-- ent improvements, 136 indicates-a rewinding roller eyhnderwhieh is mounted between cranks 109, carried by a shaft 110, I

e position shown in the cranks =-109and links 110' the uprights 123 124 above the mandrel 122,

the ends of its shaft 135 being fitted in sliding blocks 137 138, whichfit between said uprights in such manner as to move readily vertically to adjust the vertical position ofthe roll 136. Screw-clamps 139' are provided, by which the blocks 137 138 may be secured at various heights.

Asbest shown in Fig. 4, the shaft 135 carries'near each end of the roll 136 a sprocketwheel 140, which sprocket-wheels are connected, respectively, by chains 141 with sprocket-wheels 142, .mounted upon a shaft 143, arranged parallel with the roll 136 and journaled in the ends of connecting-rods 144 145, which are pivoted to the end portions of the shaft 135. It will thus be seen that the shaft 143 may swing in the arc of a circle about the shaft 135 as a center and that such swinging of the shaft 143 will not affect the 'operation of the chains 141, through which the shaft 135 is rotated, as hereinafter described. J The shaft 143 is also pivotally connected with the axis 146 of thcylinder by connecting-rods 147 148, as best shown in Fig. 1, so that the shaft 143 also swings about the axis 146 as a center. The shaft 143 is driven from the oylinderQO by means of a s rocket-chain 149, which is fitted upon a sproc et-wheel 150, mounted. upon the axis 146 of the cylinder 90, near one end thereof,

and around a sprocket-wheel 151, mounted upon the shaft 143, as shown in Fig. 4. Oh-

-v1ousl when the cylinder 90 rotates in the direction indicated b the arrow in Fig. 1

the shaft 143 is cause torotatein the same direction, such motion being transmitted through chain 141 to roll 136, which is also driven in the same direction as the cylinder 90.

The length of the connecting-rods 145 and 148 is such that when they are approximately in line the roll 136 is at the outer or up er ends of the uprights 123 124. The roi 136' may, however, moveinwardly or descend so as to lie close to the cylinder 90, the

connecting-rods 145 and 148 then assuming an acute angular position with reference to,

each other, as shown in Fig.1. In practice the roll 136 is raisedsufficiently to permit the mandrel 122 tobe inserted between said roll and the surface of-the cylinder 90 ,so that I the fabric wound upon the mandrel is en gaged by said roll and cylinder, the; roll 136 engaging its upper surface, wnile the cylin-v der 90 engages'its lower surface. ,Conse quently friction is applied to the fabric at both points as it is being rewound thu equalizingthe power applied to therollandinsuring the smooth rewindin'g of the fabric The speed of the roll 136 may be regulated at pleasure by varying the size of one or more of the different sprocket-wheels; but, ordi narily adjustment is not necessary, as after thepartsare'once' adjusted no further change is ordinarily required. Preferably the roll pended by chains'or cables 152 from drums 153, mounted near the ends of a shaft 154, j ournaled in suitable bearings 155, secured to the upper ends of the u rights 123, as 'best shown in Fig. 3. Said s aft- 154 is provided at one end with a gear 156, which meshes with a pinion 157, mountedon a stud 158,

fixedly secured to and projecting from one of the uprights 123, asbest shown in Figs. 3 and 5. The pinion 157 is connected. by a sleeve 159 with a hand-wheel 160, by which it may be rotated to rotate the shaft 154; A sleeve 161 connects the pinion 157 with a ratchetwheel 162, also mounted on the stud 158, as best shown in Figs. 3 and 5. The object of the ratchet-wheel 162 is to provide for lock- Q ing the roll 136 in an elevated position, and

to this end a pawl 163 is provided, whichis pivotally mounted upona fixed pivot 164,

' carried by the upright 123, adjacent to the ratchet-wheel 162.. The pawl 1.63 is'pro- -vided with an extended arm or lever 165, as

bestshown in Fig. 5, to whichis connected a spring 166, which operates to hold up the ,arm 165, and consequently holds the pawl 163 yieldingly in contact with the ratchet wheel. A chain or cord 167 depends from the arm 165 for conveniently depressing said arm and releasing the ratchet-wheel 162 from the pawl 163, thereby permitting the roll 136.

to descend.

- When the mandrel is to be removed or put in place, the roll 136 is elevated by means of the hand-wheel 160 and is retained in its ele- 'VSLt-OdJOSltiOIl by the ratchet mechanism describe By pulling the chain 167 the roll 136 is released and descends to its operative position.

In re'winding certain very light fabrics,

I such as silks,,it is desirable to provide means by which the tension upon the rewindingroll may be accurately regulated and adjust ed, and for this purpose in addition to the mechanism already described I have provided the further improvements shown principally in Figs. 7 and 8. The latter mechanism is inthe form of an attachment adapted to be connected up with the rewinding mechanism illustrated in Figs; 1, 2, and 3 in the manner shown in Fig. 7. Such attachment consists of two parts adapted to be secured at the opposite sides of the machine between the uprights 123 124. The attachment which s applied to the left-hand side of. the machine, as illustrated in the drawings, consists of a block 168, adapted to fit between the uprights 1'23 124, having its edges. grooved for that purpose, as shownin Fig. 9.

' sprocket-wheel 176.

It is also provided with a projecting flange .169 at its upper ed 'e, which projects over the in Figs. 8 and 9. The block 168 carries near its lower end a shaft 171, which is arranged perpendicularly-to the block and projects beyond the inner fa 3e thereof, as shown in Fig. 8. The outer end of the shaft 171 is journaled in a bearing 172 in the outer end of a bracket 173, which is preferably formedintegral with the block 168 and rojects later-' ally therefrom, its outer end being 'bent downward to receive the shaft 171. ed upon and keyed to the shaft 171 between the bearing 172 and the block 168 is a sleeve 174, having at or near its inner end a radial flange 175. I

, 176 indicates a sprocket-wheel mounted upon the sleeve 17 4 adjacent to the flange 175. Between said flange and said sprocket-Wheel,

which is in the form of a disk, is packing 177,

of leather or other suitable material, adapted to frictionally engage the adjoining surface of the flange 175 and sprocket-wheel 176.

178 indicates a second sleeve, which is mounted on the sleeve 174 and is provided with a radial flange 179, which is adjacent to the outer surface of--the sprocket-wheel 176,

180 indicates friction packin between the flange 179 and the outer sur ace of the The sleeve 178 is movable longitudinally uplon the sleeve 174 to cause the sprocketw eel 176 to be engaged more or less tightly between flanges 179 and 17 5.

When. great pressure is applied to the sprocket-wheel 176, the sleeve 174 may be caused to rotatewith the sprocket-wheel 176 at an equal rate of speed, and such speed may be reduced to any desired extent by simply releasing the pressure upon' said sprocket-wheel. Since the sleeve 174 is keyed upon the shaft 171, the speed of said.

shaft depends upon the speed of said sleeve.

In order to control such. pressure, I provide a hand-wheel 181, which. is screwed upon the outer end of the sleeve 174, asshown in Fig. 8, and bears against the outer end of the sleeve 178. I thus providea friction-clutch Mountby which the speed of the shaft 171 may be I controlled without regard to the speed of the sprocket-wheel 17 6.

The sprocket-wheel 176 is driven fromthe shaft 135 of the rewinding-roll 136 by means of a pinion 182, which is mounted upon said shaft and mesheswith a pinion 183, mounted on a stud 184, carried in the upper portion of the block 168, as best shown in Fig. 8. Said shaft 135 is connected with a sprocketwheel 186, which sprocket-wheel is connected by a chain 187 with sprocket-wheel 1-76.

Thus the shaft 1.35 drives the sprocketwheel 176.and through it the shaft 171.

The attachment at the opposite side of the machine consists of a block 188, similar to the block 168 in thatit isprovided with a flange 189 at its upper edge adapted to be secured by a bolt 190 to the block 137. The

I block, 188 also fits between the uprights 123,

A chine.

124. and rests upon the frame 200'! the ma The construction of the block 188 is best shown in Fig. 11. Saidblock carries an endwise-movable pin 191 which is adapts ed to project beyond the inner surface of said block and is provided at its outer end with.

a hand ,iece 192,. by which it may be con venlent y operated. Said in 191- is in line with the shaft 171 and wit the projecting inner end of said shaft serves to axially support arewinding-mandrel 193, as best shown in Fig. 8. The inner endsof the shaft 171, and preferably that of the pin 191, are squared, so as to compel the mandrel 193 to rotate with the shaft 171. The mandrel 193 is put in place or removed by drawing out the pin 191, so as to permit the mandrel to be fitted upon the end of the shaft 171. or

removed therefrom, as desired. When .the mandrel is in place, the pin 191 ismoved to 1t s innermost position, where it fits in the socket provided for that purpose in the end of the mandrel and secures the mandrel in position. To prevent the pin 191 from accidentally moving outward, I provide a latch. 194, pivoted to the block 188-adjacentto the pin 191 and adapted to swing down beyond a shoulder 195, formed by reducing the outer portion of the pin, as best shown inFigs. 8 and 10. When the pin is in its innermost position, the shoulder 195 lies flush with the outer surface of the block 188, and the latch 194 then extends beyond said shoulder, as shown in Fig. 10. The latch 194 is swung aside when the pin is to be drawn out.

With the attachment described all that is necessary to regulate the speed of the mandrel is to adjust the hand-wheel 181 to increase or reduce the friction upon the sprocket-wheel 176. Consequently the tension on the fabric may at all times be accurately regulated.

While m improved rewinding device is especially esigned and arranged to cooperate with devices for applying composition to the fabric, so as to receive and rewind the fabric as it comes from the calendering-cylinders, as has been suggested, in its broadest aspect it is not restricted to use with such apparatus. Neither is my invention restricted to the specific details of the construction illustrated and described, except in so far as they are particularly claimed, as it includes,

generically, the subject -matter of the roader c aims While the-r ll 136 issh as being may move inwardly or outwa ly in any other suitable lane.
